Convert kilowatt-hour to kilojoule
Please provide values below to convert kilowatt-hour [kW*h] to kilojoule [kJ], or Convert kilojoule to kilowatt-hour.
1 kW*h = 3600 kJ. To convert kilowatt-hour to kilojoule, multiply the value by 3600; to go the other way, divide by it (1 kJ = 0.000277777777778 kW*h). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kW*h = 3600 kJ
- 1 kJ = 0.000277777777778 kW*h
- 10 kW*h = 36000 kJ
- 100 kW*h = 360000 kJ
How to Convert Kilowatt-Hour to Kilojoule
1 kW*h = 3600 kJ
Example: convert 15 kW*h to kJ:
15 kW*h = 15 × 3600 kJ = 54000 kJ

Kilowatt-Hour
A kilowatt-hour (kW·h) is a unit of energy equal to the energy transferred or used when a power of one kilowatt is sustained for one hour.
History/Origin
The kilowatt-hour originated in the late 19th century with the development of electrical power systems, becoming a standard unit for measuring electrical energy consumption and billing.
Current Use
It is widely used today in electricity billing, energy consumption monitoring, and in various engineering and scientific applications to quantify electrical energy usage.
Kilojoule
A kilojoule (kJ) is a unit of energy equal to 1,000 joules, used to quantify energy transfer or work done.
History/Origin
The kilojoule was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring energy, especially in fields like nutrition and physics, replacing the joule for larger quantities.
Current Use
The kilojoule is widely used in nutrition to express food energy content, in physics and engineering to measure energy transfer, and in various scientific and industrial applications within the 'Energy' converter category.
